Abstract
Objective : This study was designed to find out influential factors associated with Hospitalization of the patients who were divided into group A and group B, all of whom had admitted to the Korean medical hospital due to traffic accident. Patients in group A were diagnosed with a mere ‘sprain’, and patients in Group B had other symptoms(Headache, Nausea & vomiting, Dyspepsia, Insomnia, Palpitation, Dizziness) accompanied by ‘sprain’.

Methods : : Based on the medical charts, we analyzed statistical study of 486 patients putting them into two groups who had admitted to Department of Korean Rehabilitation Medicine, Dunsan Korean Medical Hospital of Dae-Jeon University during the period between January 1, 2015 and September 1, 2015.

Results :
1. In group A, cervical sprain was observed the most and male patients with the symptom outnumbered female patients. In group B, headache was found most frequent where female patients had the symptom 1.7 times more than male patients. Average age of patients in group A was higher and these patients stayed longer in hospital compared to those in group B.
2. From the Hospitalization analysis based on sex, female patients in group B were found to stay for a longer period of time in the hospital than the male counterparts (p<0.05).
3. Both group A and B have positive correlation between length of hospital stay and age though group B exhibited stronger correlation.
4. In Hospitalization analysis based on the types of accident, patients who had accident while riding bus in group A and those who were pedestrians in group B were found to stay in the hospital for a significantly longer period of time than those who had any other types of accident (p<0.05).

Conclusion : We noticed that hospital stay lengthened when the patients were older and when they had accidents while riding bus in Group A whereas in Group B, patients stayed longer when they were females and older as well as when they were pedestrians in accidents. Further studies such as research on clinical trials are needed to find effective Korean medical treatment based on groups.
